Definitions
- the present invention relates to a metal complex which can be used in the preparation of an asymmetric compound useful in the fields of medicines, agricultural chemicals, perfumes, liquid crystals, and the like. More particularly, it relates to a metal complex by which an optically active reaction product having high optical purity can be obtained in high yield when it is used as a catalyst for asymmetric Michael addition reaction, asymmetric hydrophosphonylation reaction, or the like, as well as a process for producing an asymmetric compound using a solution of the metal complex.
- the present inventors previously studied an asymmetric synthesis reaction using a metal complex catalyst of a rare earth metal element and, as a result, found that a metal complex prepared by a method of mixing lanthanum chloride (LaCl 3 ) and optically active dilithium binaphthoxide in tetrahydrofuran and adding water and sodium hydroxide thereto, or by a method of successively adding optically active binaphthol, water, and lithium chloride to a solution of La 3 (O-tC 4 H 9 ) 9 (lanthanum t-butoxide) in tetrahydrofuran containing sodium tert-butoxide, can catalyze an asymmetric nitroaldol reaction to afford a nitroaldol product having high optical purity (J. Am. Chem. Soc., Vol. 114, p. 4418 (1992)).
- La 3 (O-tC 4 H 9 ) 9 lanthanum t-butoxide
- a metal complex i.e., La--K-Binol (LPB)
- LPB La--K-Binol
- La--Li-Binol (LnLB)
- LnLB La--Li-Binol
- lanthanum which is a rare earth metal element contained in the aforementioned metal complexes, is difficult to obtain and, thus, the development of metal complex catalysts without using a rare earth metal is desired.
- metal complex catalysts are not yet known.
- an asymmetric Michael reaction product and an asymmetric ⁇ -hydrophosphonylated compound are both known as useful asymmetric compound reaction products.
- a hydroxy phosphorylated compound has potent bioactivity and is expected to act effectively as an enzyme inhibitor for a synthesis enzyme such as renin, EPSP synthase, HIV protease, and the like and, thus, the development of an optically selective process for synthesizing these asymmetric phosphorylated compounds is desired.
- Ln--Li-Binol Ln--Li-Binol
- the present invention provides a metal complex, or a solution of the metal complex, that can be used as a catalyst in an asymmetric Michael reaction and in an asymmetric hydrophosphonylation reaction, contains no rare earth metal element, and can afford an optically active compound having high optical purity at high yield.
- the present invention also provides a process for producing an asymmetric compound by an asymmetric Michael reaction and an asymmetric hydrophosphonylation reaction using such the metal complex.
